Context

• This was a sale (liquidity event) rather than a purchase; sales by executives can be routine (personal liquidity, diversification, tax obligations, etc.) and do not by themselves indicate company performance. No 10b5‑1 plan, gift, or option exercise was reported in this filing. Retail investors should view this as factual disclosure of insider selling rather than a directional endorsement.
